Disney has been rolling out a whole line of kids digital books with its DigiBooks for a while, and a few selected comics on iPhone, but now they have their own app selling comics from the range of their 80 years history — from Donald Duck to High School Musical. According to the PR, Disney comics have over 1 billion readers worldwide.

Don’t underestimate the power of “kidgital” content.

Disney Publishing Worldwide announced today its new Disney Comics App for iPad, iPhone and iPod touch is now available on the App Store. Disney Comics gives readers instant access to one of the most extensive collections of comics, short stories and graphic novels ever created, ranging from classic adventures starring Mickey Mouse to brand new comics from Toy Story and Cars 2.

The launch collection includes more than 50 comics for readers of all ages and features Disney classic characters like Donald Duck; Disney-Pixar comics featuring Toy Story’s Buzz and Woody; Disney Channel-inspired content including High School Musical; and feature film-based comics based on Tron: Legacy and Tangled. Disney Publishing will release two new titles each week following the launch.

The Disney Comics App will launch in the U.S. and will also be available on the App Store in over 80 countries across the Americas, Europe, Asia, Africa, and Australia. Additional markets will launch Disney Comics later this year.

“Comics are a tremendous part of our heritage and we see great potential and interest in bringing our extensive catalog of Disney Comics to mobile devices,” said Russell Hampton, President, Disney Publishing Worldwide. “We create over 25,000 original comic pages each year and it’s critical that we deliver this content to our readers around the world. We have over 1 billion Disney comic readers today, and our Disney Comics App will further broaden that audience.”

The Disney Comics App offers a new, director-style reading experience; readers can choose portrait or landscape mode, automatic or manual smart paneling, and can view double spreads. Disney Comics also enables readers to preview comics before making a purchase, share their stories with Facebook friends, and save all content to their iPad, iPhone or iPod touch for offline reading. An added feature lets readers receive automatic updates when stories relating to a favorite Disney character become available.

The Disney Comics App is available for free from the App Store on iPad, iPhone, and iPod touch, or at www.itunes.com/appstore. Individual stories are $.99 and themed bundles are available for $3.99 through In-App Purchase.
